It is designed for motor control and resistive load switching across utilisation categories AC-1, AC-3, and AC-4. The latching mechanism holds the main contacts closed without continuous coil power — the coil draws 550 W only during the 40–80 ms latching pulse, and 60 W during the 50–100 ms unlatching pulse, after which the coil is de-energised. This makes it suited for applications where sustained coil power is undesirable or where the contactor must stay closed through a control-power interruption. The 500 A AC-3 rating governs motor switching — this is the current the contactor can make and break across a typical induction motor load. The AC-1 rating for resistive loads is higher at 700 A, and the AC-4 rating for inching/plugging duty is 460 A. The rated breaking capacity is 5000 A at 220–440 V, dropping to 2500 A at 1000 V, which tells you the maximum fault current the contactor can interrupt without damage. The rated short-time withstand current (Icw) is 4200 A for 1 second at 40 °C, so the contactor can hold through a downstream short-circuit until an upstream protective device clears. The rated insulation voltage (Ui) is 1000 V per IEC 60947-4, and the rated operational voltage (Ue) is 1000 V AC at 25–200 Hz. ## Coil and control circuit specifics The control circuit is DC low-consumption type at 48 V nominal. The coil operates reliably between 0.85 and 1.1 times Uc for both latching and unlatching. Average consumption is 550 W during the latching pulse and 60 W during unlatching — after the pulse, the coil draws nothing. This is a key difference from a standard contactor that must be continuously energised to stay closed. The operating time is 40–80 ms to close and 50–100 ms to open, which is typical for a large-frame contactor of this rating. ## Physical integration and wiring The contactor measures 232 mm deep, 233 mm wide, and 238 mm high — a substantial footprint that requires adequate enclosure space and clearance for cable bending. Power connections accept lugs or ring terminals up to 240 mm², or bars up to 40 x 5 mm. The tightening torque for main connections is 35 N.m. The associated fuse recommendation is 500 A aM or 800 A BS88/gG at up to 440 V. The protective treatment is TC (tropicalised coating), which adds corrosion resistance for humid environments. ## Durability and thermal performance The maximum operating rate is 120 cycles per hour at 40 °C. Power dissipation per pole is 45 W in AC-3 duty and 88 W in AC-1 duty — this heat must be considered in enclosure thermal calculations. The average impedance per pole is 0.18 mOhm at 700 A, 50 Hz, which gives a voltage drop of roughly 0.09 V per pole at rated current.","metaTitle":"TeSys F CR1F500EZ7 Magnetic Latching Contactor, 500 A, 48 V","metaDescription":"TeSys F CR1F500EZ7 magnetic latching contactor, 3-pole 500 A AC-3, 48 V DC coil.
